Patent EP-0375588-A1 (EP)
Inventor: AGHAJANIAN MICHAEL KEVORK
IPC: C04B41/88
Filed: 1989-11-09
Abstract: The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer pre­cursor and/or an infiltrating atmosphere are in communica­tion with a filler material (2) or a preform, at least at some point during the process, which permits molten matrix metal (3) to spontaneously infiltrate the filler material (2) or preform. Such spontaneous infiltration occurs with­out the requirement for the application of any pressure or vacuum.

Abstract: La présente invention décrit un convertisseur continu-continu capable de fonctionner à partir d'une source d'alimentation dont la tension de sortie peut varier selon un rapport de 10 à 1. Un transistor de commutation (52) est utilisé pour convertir la tension d'entrée du courant continu en une tension pulsée. Des techniques de régulation par action directe sont utilisées pour compenser rapidement les variations d'amplitude de la tension d'entrée. Des techniques de rétro-action sont utilisées pour maintenir la tension de sortie à la valeur désirée. Une isolation entre l'entrée et la sortie est assurée au moyen d'un transformateur (50) destiné à coupler les circuits de commutation à un redresseur (92) et à un filtre (94, 95), lequel produit la tension de sortie. Une liaison à fibre optique (153) assure l'isolation pour le signal de rétro-action.

Abstract: An antenna radome (12), suitable for use with high precision, environmentally sensitive array antennas (10), includes a dielectric sheet (20,22) formed to protect the antenna from environmental conditions and a series of conductors (16) fixed on the sheet in a certain pattern so that the sheet with the conductors provides a lower reflection coefficient to electromagnetic waves at the antenna's operating wavelength than in the absence of the conductors. Current is caused to flow through the conductors (16), thus generating heat in areas of the dielectric sheet (20,22) where the conductors (16) are fixed. Accordingly, ice formation on the protective dielectric sheet can be prevented while the antenna array is operational, and accurate antenna performance is ensured. Further, the dielectric sheet presents a significantly lower reflection coefficient at the operating wavelength than radomes in which a conventional grid of heater wires is provided for melting ice.

Abstract: A method for recovering tungsten from a tungsten containing spent catalyst comprises digesting the catalyst in aqueous sodium hydroxide solution wherein the mole ratio of the sodium hydroxide to the tungsten contained in the spent catalyst is from about 2.6 to about 4.2 and wherein the amount of water is sufficient to dissolve the subsequently produced sodium tungstate, at a temperature of at least about 90 o C for a length of time of at least about 1 hour to convert greater than about 77% by weight of the tungsten contained in the spent catalyst to sodium tungstate and form a sodium tungstate solution thereof and a residue containing the balance of the starting tungsten, and separating the sodium tungstate solution from the residue. Essentially all of the tungsten is recovered as sodium tungstate by first grinding the catalyst prior to the digestion and by using a mole ratio of sodium hydroxide to tungsten of about 3.8 to 4.2.
